BACKGROUND

Multimedia is media and content that utilizes one or more content forms. For example, multimedia can include text, audio, still images, animation, video, and interactivity content forms. Multimedia can be transmitted over a network, such as an Internet, and be used to communicate. For example, digital photos can be posted as a photo album online for viewing by any member of the public. In another example, a user can utilize a digital photo as an online avatar (or representative icon) in user transactions online.

Digital images can be obtained in a variety of ways, including from a digital camera, a scanner scanning a physical paper, or via various graphical applications for creating digital imagery. Such digital images can be stored in a variety of standard Raster file formats, including JPEG, BMP, TIFF, RAW, PNG, and GIF. Alternatively, digital images can be stored in vector formats, such as CGM and SVG.

Media including digital images can be manipulated via various operators, which create or enhance media characteristics. Example operators for images include transforming, clustering, diffusion, filtering, and thresholding. For example, filtering can removing undesired characteristics within an image, such as a specific color or brightness.

Multiple operators can be combined to form effects that alter a digital image in a predetermined manner. For example, an effect for converting a color image to a black-and-white image for transmission over the Internet can crop the image to a manageable size, remove noise from the image, and convert brightness of image pixels into a grayscale pixel. The effect thus provides a black-and-white image ready for distribution over the Internet.

A graphical user interface (GUI) is a type of user interface which allows people to interact with electronic devices such as computers; hand-held devices such as MP3 Players, Portable Media Players or gaming devices; household appliances and office equipment. A GUI offers graphical icons, and visual indicators, as opposed to text-based interfaces, typed command labels or text navigation to fully represent the information and actions available to a user. The actions are usually performed through direct manipulation of the graphical elements via devices such as pointer devices.

Thus, there is a need to provide an improved user interface allowing designers to easily design effects from pre-existing operators, and to provide the effects to users over a network from a server.

DETAILED DESCRIPTION

A graphical user interface allows designers to create effects from available operators. For example, image operators are coded by developers to manipulate digital images and compiled into an operator library. The operator library is compiled and distributed to the designers along with a GUI executable. The designers utilize the GUI to define a desired effect via manipulations of available operators. For example, an effect can be defined by specifying which operators are used, the order in which the operators are used, and operator parameters. Once the effect is defined, an effect definition is created and uploaded to a server. The server makes the effect available to users over a network. Example effects can include converting a user-provided image into a cartoon

FIG. 1 illustrates an example process for providing user-accessible effects. The process can execute on a system as illustrated in FIG. 2. The example process depicts interactions between developers, designers, and users from creation of new operators, defining a new effect, and making the effect available to users over a network. The upper portion of the figure can execute in a distributed manner, for example, at a developer or designer's workstation. The lower portion of the figure can execute on an effects server.

In 100, a developer conceives and codes a new operator. The operator can be coded in a programming language such as C++ and exploit CPU and GPU capabilities.

[Please include brief description of each example operator] Example operators include transforming, clustering, diffusion, filtering, and thresholding. Example transform procedures include fft_image3D, inv_fft_image3D, correlation_fft_image3D.

Example clustering operators include cluster_disjoint_universe_image and cluster_image_kmeans.

Example diffusion operators include anisotropic_diffusion_image and coherence_enhancing_diffusion_image.

Example filtering operators include generalized_kuwahara_image, bump_emboss_image, and simulate_radial_motion_image, wiener_image.

Example thresholding operators include get_local_entropy_threshold_image, get_joint_entropy_threshold_image, get_global_entropy_threshold_image, smooth_threshold_image, solve_system_image_svd, and solve_system_image_lu.

Example geometric operators include fit_bezier, fit_line, and fit_circle, fit_ellipse.

Example fast region operators include connection_region.

Additional operators can be coded by developers as desired.

In 102, a core library is recompiled with the new operator of 100. The library is then distributed along with a GUI executable providing a GUI for combining operators into effects. In one example embodiment, updates are distributed as patches to the library and/or the executable.

In 104, a designer utilizes the core library and included operators to design an effect. The executable can provide a GUI allowing a designer to create an effect by defining which operators to use, in what order to use the operators, and define parameters for the operators. For example, an effect can be designed via a user interface as depicted in FIGS. 4A to 4F.

In 106, the designer saves the effect designed in 104 as an effect definition. For example, the GUI executable can allow the designer to preview the effect as applied to one or more test images. Once the designer is satisfied with the effect, the effect is saved as an effect definition. For example, the effect definition can define the effect in terms of operators and parameters. The effect definition is uploaded to the server.

In 108, the server automatically generates a script language module from the effect definition. For example, the scripting language can support low-level communication between operators and the library and enhance performance. The script language module can be a translation of the uploaded effect definition.

In 110, the server updates relevant application programming interfaces (API). The API can interface between user requests received over a network and the script language module created in 108.

In 112, the effect is made available online. Users are able to select an effect, upload images, and receive a processed image in accordance to the effect. For example, effects can be accessed by users via a user interface as depicted in FIGS. 5A to 5F.

FIG. 2 illustrates an example system for providing user-accessible effects. A terminal 200, such as a personal computer or other computing device, is accessible to a user 202. The terminal 200 can execute a web browser or another application to interface with other computing devices. The terminal 200 can be as illustrated in FIG. 6.

The terminal 200 communicates with a server 206 over a network 204. The network can be any network configured to carry digital communications, such as the Internet. The server 206 can be a computing device configured to serve one or more terminals, as illustrated in FIG. 7.

The server 206 is in communications with a memory 208. The memory 208 can store computer-readable instructions for providing an interface to generate a cartoon responsive to predefined algorithms and user-provided parameters. The computer-readable instructions can be part of an effects module 210, discussed below.

It will be appreciated that functionality providing effects can be split between the server 206 and the terminal 200. For example, simple pre-processing of the image, such as cropping or color correction, can occur at the terminal 200. More intensive processing can occur at the server 206.

In FIG. 2, in operation, the user 202 submits an image 212 to the server 206 for processing. The user 202 interacts with the server 206 via an effects user interface. Processing includes adding effects to the image. The server 206 executes the module 210 with parameters received from the user 202, which processes the image 212. A resulting processed image 214 is provided back to the user 202. It will be appreciated that no physical transmission of the image 212 or processed image 214 is necessary. For example, URL addresses can be provided, allowing the terminal 200 and the server 206 to retrieve relevant files from locations accessible over the network 204.

FIG. 3 illustrates an example procedure for providing user-accessible effects. The procedure can execute on a designer terminal, as illustrated in FIG. 6. The designer terminal can allow a designer to define an effect from existing operators, and then upload the defined effect to a server that provides the effect to users over a network. The operators and effects can be as discussed above.

In 300, the terminal optionally receives a GUI executable. As discussed above, a GUI executable can be distributed by developers along with a library of available operators. The GUI executable can be configured to provide a GUI allowing a designer to design an effect, as illustrated in FIGS. 4A to 4F.

In 302, the terminal tests whether the library of operators has been received. As discussed above, the library can be received along with the GUI executable, or separately. The library can be compiled by developers and include all pre-defined operators available to the designer.

If the library has been received, the terminal proceeds to 304. If the library has not been received, the terminal can wait at 302.

In 304, the terminal tests whether an effect definition has been received from a GUI. The terminal can provide a GUI to the designer, for example, by executing the GUI executable received in 300. The GUI can receive designer inputs specifying a new effect, such as which operators to use, in what order the operators are used, and parameters for each operator.

If the effect definition has been received, the terminal proceeds to 306. If the effect definition has not been received, the terminal awaits designer input via the GUI at 304.

In 306, the terminal optionally previews the effect definition as applied to a test image. For example, the designer can specify an image on which to test the effect definition as inputted in 304.

It will be appreciated that the designer can return to 304 to revise the effect definition after previewing.

In 308, the terminal saves the effect definition received in 304 and previewed in 306 to memory. For example, the effect definition can be saved to volatile or non-volatile memory accessible to the terminal, locally or over a network.

In 310, the terminal uploads the effect definition received in 304 and previewed in 306 to a server. The server can be as illustrated in FIG. 7 and process the effect definition into a module accessible to users over a network.

In 312, the terminal exits the procedure.

FIG. 4A illustrates a first example screen shot of a GUI allowing a designer to design an effect. The GUI can be displayed on a terminal to a designer as illustrated in FIG. 6. The terminal can upload an effect definition created by the designer to a server as illustrated in FIG. 7.

The GUI includes tools 400 for the user to define the effect. The tools can include a delete, select, move, a zoom, and other tools.

The GUI includes an input/output portion 402. The input/output portion 402 can allow a designer to specify an input image to use and an output image to write a processed image to.

FIG. 4E illustrates a fifth example screen shot of a GUI allowing a designer to design an effect. The screen shot can be similar to that illustrated in FIG. 4A. The GUI can allow the designer to rename a node in a window 440. It will be appreciated that the GUI can also allow the designer to rename the effect definition.

FIG. 4F illustrates a sixth example screen shot of a GUI allowing a designer to design an effect. The screen shot can be used to debug an effect definition. The screen shot illustrates an operator parameter input area 450. If the designer does not wish to utilize the GUI, parameters can be manually inputted as text. During execution or preview of the effect, the designer can examine parameter value in area 452. For example, specific parameters can be added to a watch list. The effect definition can also include a script version of the effect in program window 454. This allows the designer to view and modify a script language version of the effect.

It will be appreciated that screen shot can illustrate a more advanced interface for designers desiring more control over the definition process. By removing the GUI, more parameters are accessible to the designer for manipulation.
